METALLIC BEAM SPLICE.

Application filed February 9, 1923.

T iiZZ whom it may concern c it known that I, JOHN MAYOT'IE, a citizenof the United States, and resident of (.ldanah, in the county of Ashlandand State of lVisconsin, have invented certain new and usefulImprovements in Metallic Beam Splices; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

This invention relates to metallic beam splices, and is particularlydirected to a splice applicable to building beam or building structurejoints, to rail connections for tracks and for similar purposes.

Objects of this invention are to provide a metallic beam splice whichhas a double lock joint which will continue to hold the beam or railsfrom relative turning motion, although the bolts and fish-plates mayhave become detached.

Further objects are to provide a metallic beam splice which is soconstructed that one beam end may not be lifted directly upwardly fromthe other, although the attaching bolts may have become removed, whichwill prevent spreading of rails, and which is still, self sup-portingand strong.

Although the invention is applicable to several diiierent uses, it hasbeen illustrated in the accompanying drawings as applied to a railjoint, and in such drawings- Figure 1 is a side elevation of the joint.

Figure 2 is a plan view of the structure shown in Figure 1.

Figure 3 is a section on the line 33 of Figure 2.

Figure 4 is a plan view of one of the rail ends.

Figure 5 is a ing rail end.

Referring more particularly to the drawings, it will be seen that a pairof rail ends have been illustrated, such rails comprising a web 1, abase or flange 2, and a head 3. For convenience of description, thecorresponding portions of the right hand rail in Figure 1, have beenindicated 1, 2 and 3, respectively. These rails are arranged with theirends juxtaposed, and are cut away, as indicated in Figures d and 5. Oneof the rails, for instance the left hand, has its web 1 cut out, and theone side of the head 3 cut away, thereby leaving a projecting tongue 41.The flange 2, is similarly plan view of the cooperat- Serial No.617,961.

It is to be noted from reference to Figures 3 and 4, that the tongues 4:and 5 are arranged upon opposite sides of the center line. cooperatingrail up to the web 1',

The corresponding end of the has its web 1 left intact. However, aportion of the head is cut away thereby leaving a projecting portion 6integrally joined to the web and extending only to one side thereof. Theflange is similarly cut away on the opposite side of the web,

thereby leaving a projecting portion 7 integrally joined to the web andextending therefrom in an opposite direction of the portion 6, a

In assembling the rails,

It is, therefore, to be understood that al- 7 though one form of theinvention has been described in considerable detail, the invention maytake other forms and is to be limited only as defined in the appendedclaims It is further to be understood that the. term beam, as used inthese claims, is to be understood as covering the usual beamconstruction, railway rails, and other similar articles.

I claim:

1. In a beam splice, the combination of a pair of juxtaposed beam endshaving interlocking tongues positioned upon opposite sides of a centralweb, a pair of fishplates bolted through such web, one of said endshaving the web wholly cut away adj acent s ch end and the other endhaving a web adapted to fit within the cut away portion.

2. In a metallic beam splice, the combination of a pair of juxtaposedbeam ends each having a head, a web, and a lower flange, each of saidends having a tongue forming a continuation of said head and flangerespectively, and said head and flange being cut out adjacent saidtongues to receive the corresponding tongues of the other beam end, oneof said rail ends havingthe web cut away adjacent the tongue, and theother 01 said ends having the web in position adjacent its tongue andintegrally joined therer to, whereby said ends may be interlocked toform a substantially continuous head and flange adjacent said tongues,and a pair of fish plates bolted through the webs of the adjacent railends.

In testimony that I claim the foregoing I have hereunto set my hand atOdanah, in the county of Ashland and State of Wisconsin. 7

JOHN MAYOTTE.
